MK2746
REV A 100802
Description
The MK2746 is a low cost, low jitter, high performance clock
synthesizer for DVD and other MPEG2 based applications.
Using analog Phase Locked Loop (PLL) techniques, the
device accepts a 27 MHz fundamental mode crystal or
clock input to produce multiple output clocks including the
processor clock, audio clock, bus driver clock, SDRAM
clock and a Video clock. The audio clocks are frequency
locked to the 27 MHz input using our patented zero ppm
error techniques, allowing audio and video to track exactly,
thereby eliminating the need for large buffer memory.
ICS manufacturers the largest variety of DVD, set top box,
and multimedia clock synthesizers for all applications.
